3 beginner questions!

[Ali Dada]

thanks all for your ideas on PyQt: they got me going!!

but the problem with Tkinter (question 2) is still not solved. i
tested Rene's code but it still didn't work. and by the way, i tried
to run a PyQt-generated window from a Tkinter window but the former
messes up the latter and rendered it unusable. any ideas on mixing the
two libraries in my application or is it an unrecommended approach??
thanks again for your help!!
